GC-7890 gas chromatograph

1. Large screen LCD Chinese display, real-time display of various temperatures and operating conditions, clear and intuitive content, truly realizing human-machine dialogue;

2. Power on self-test, wide range self diagnostic function, can accurately determine the fault location and alarm;

3. Six independent temperature control channels (vaporization chamber and capillary vaporization chamber can independently control temperature), with eight step programmed temperature rise function;

4. Overtemperature protection function: If any circuit exceeds the set temperature, the instrument will automatically power off and sound an alarm;

5. The unique vertical heating device ensures more reliable sample vaporization, minimizes the heat radiation generated by the vaporization chamber, and ensures minimal temperature deviation inside the column box;

6. Intelligent fuzzy control rear door opening system, automatically tracks temperature and dynamically adjusts air door angle, truly achieving near room temperature operation

7. Configure a capillary split/non split injection device with filling column head injection and glass lining injection, equipped with diaphragm cleaning function, and capable of installing gas injectors;
